INSULATOR.

Specification of Letters Patent. Patented Aug. 13, 1912.

Application filed March 1, 1911. Serial No. 611,566.

To all whom it may concern 4 Be it known that we, ROBERT L. BnowN and GUS BROWN, citizens of the Unlted States, residing at Mayview, in the county of Lafayette, State of Missouri, have invented a new and useful Insulator, of which the following is a specification.

" tion passing therethrough. Fig. 2 is a side elevation of the insulator taken at right angles to the position from which 1 is In the drawings the numeral 5 designates thebody of this insulator which is of glass,

seen. Fig. 3 is a central vertical section on the line 33 of Fig. 2 and Fig. 4: is a I section on the line 4-4 of Fig. 1, both Figs.

3 and 4 showing at their-right hand sides a slight modification.

porcelain, or thelike, and in the lower end of this body is a cavity 6 such as is usually intended to hold and insulate two conductor wires, and it is of course desirable that these wires shall stand so remotejfrom each other between "the supports that they will not come in contact under the influence of the elements.

' 'Through the body is formed what might By preference they are more than twice .as-

. tall as the diameter of the .wire', and a little wider than the'said diameter, sothat the wire when it passes through them is free laterally to rise as seen at; the right side of the insulator.

Fig. 3 or to fall into the lower end of the opening as elsewhere shown. These openings 8 extend straight through the body of the insulator between its upper and lower ends and are parallel with each other, and each opens outward through the side of the body in a slot 9 communicating at its inner end with the opening at about the-center of the height of the latter, as best seen inFigJ 2. Between its ends each slot opens downward through the bottom-.of the opening 8 in a beveled wall 10 which is continued downward and outward asshown in Big. 3 and merges into the periphery of the body 5 about at the point 11. Thiswall 10 is rather narrow at its upper. end so as to leave two lugs 12, and somewhat wider at its lower end as shown at 13 in Fig. 2 and where the lugs, are undercut'as at 14 in Fig. 3.

The numeral 20 designates two spring tongues, such as strips of resilient metal, which are the only fastening means necessary with this insulator to hold the two line wires L in place. .Each tongue is of a width to pass between the inner faces of the lugs 12, and of such length that its upper end will stand beneath 'theoverhanging lip 21 along the topof an opening 8 when its lower portion is secured to the body 5 of v This lower end may be secured to the body of the insulator in a variety of Ways, of which we have illustrated two.. Perhaps the simplestis /to mold 01' embed the metallic tongue in the glass as shown at 22 at the leftof Figs. 1 and 3, although obviously this would not permit the tongue to be withdrawn as for replacing it if it-shou-ld become broken. At the right of Figs. 3 and 4 we have shown the glass as provided with upright flanges 23 between w ich the lower end ofthe tongue is inserted as by-pushing it downward from above, and this would obviously permit the removal of thejtongue-when desired. The

upper end of the tongue may be sprung I under the lip 21. by forcibly flexing the exposed portion of the tongue. I

' The body of the tongudbetween its. ends lies across and normally stands somewhat remote from the beveled wall 10 and forms a retainer for the Wire L as shown at theleft:

of Fi 3. When it is desiredto remove the wire or'when the wire is being inserted) the operator by bearing. his thumb upon the tongue at the poi'nt 13"depres 's as it to the I dotted position shown at" the right of Fig. 3 so asto push its upper extremity away from the tip 21 and thus clear the throat 24 ot the opening 8 so that the wire (which of scribed construction atone side only and would support but a single wire.

d' s hat is claimed is: y i

1. 'lhe'hereindescribed insulator comprising body of insulating material having an opening across its side whose upright dimension is greater than the diameter of the wire, said opening having a throat leading out through the ride of the body beneath an overhanging lip, and an inclined wall leading downward from the bottonrof the opening between its ends, and lugs at opposite sides of the upper "portion of said wall; combined with a spring tongue se at its'lower ends to the body of said insulator and extending thence upward over and remote from said wall and between said lugs, with its upper end passing across said throat and its upper extremity engaged behind the said lip.

2. The herein described insulator comprisinga body of insulating material having an opening across its side whose upright dimension is greater than the diameter at the wire, said opening having a threat leading out through the sideoit the body' beneath an overhanging lip and an inclined wall leading downward from the bottom of the open ing between its\ ends; combined',,with" a spring tongue secured at its lower ends to the body of said insulator and extending thence upward over and remote from said wall, with its upper end passing across said throat and its upper extremity engaged behind the said lip.

3. The herein described insulator comprising a body of insulating material having an opening across its side whose upright dimensionis greater than the diameter of the wire, said opening having a throat leading out through the side of the body beneath an overhanging lip; combined with a spring tongue securedat its lower end to the body of said insulator and. extending thence upward, with its upper end passing-across said throatand its upper extremity engaged behind the said lip.

4. The herein described insulator, the same comprising a body of'insulating material having an opening along its side with a throat leading out said side under an overhanging lip, the bottom of said opening having between its ends an inclined lower wall and the-body below said wall having upright flanges projecting toward each other; and a spring tong'ue whose lower end is removably inserted between said flanges,

whose body extends upward over and remote 4 from said wall, and whose upper extremity is engaged behind said lip.

An insulator, provided with a lateral notch having a reduced inletslot and an enlarged wire receiving portion, and a resilient closure for the enlarged receiving portion disposed at the juncture thereof with the reduced inlet slot.

6. An insulator, comprising a body of i11 sulating material having an opening across its sides whose upright dimension is greater than the diameter of the line wire. said opening having a throat leading out through the side of the body, and an outwardly tensioned spring closure for said opening.

Inftestimony that we claim the foregoing as our own, we have hereto affixed our'signatures in the presence of two witnesses. ROBERT LABROVVN.
